1. Summary of basic information at 3.00 PM ADT.

Location: 29.5north 75.7west about 440 kilometres northeast of
Freeport Bahamas.

Maximum sustained winds: 120 km/h.

Present movement: north-northeast 15 km/h

Minimum central pressure: 958 MB

2. Public weather impacts and warnings summary.

Hurricane Sandy is currently north of the Bahamas and is moving
north-northeastward. Although Sandy briefly weakened to a
Tropical storm earlier today maximum sustained winds associated
With it have increased to 120 km/h bringing Sandy back to hurricane
status. During the weekend Sandy is forecast to continue to track
north or northeastward while remaining at hurricane strength. Sandy
will gradually lose some of its tropical characteristics and on
Monday it is expected to take an uncharacteristic turn to the
northwest and begin interacting with an approaching trough from the
west.

Current indications from various weather models are that Sandy could
strengthen before moving inland on the United States East Coast in
the vicinity of Delaware late Monday as a very large and powerful
storm. It is important to remember that impacts will cover a large
area well away from the center. There are various factors
Influencing the evolution of the storm and as a result there is
Still some degree of uncertainty with respect to the magnitude of
The impacts from the storm. For this reason people living in these
areas are urged to pay close attention to messages from the Canadian
Hurricane Centre and local weather forecasts and possible future
warnings throughout the weekend.

A. Rainfall.

Based on the current forecast scenario, Southern and Eastern Ontario
and Western Quebec are likely to see the most rainfall from this
system with total amounts by Tuesday evening possibly reaching the 50
to 100 millimetre range which would be typical for post-tropical
weather systems. However since post-tropical Sandy will be
interacting with a stalled front over Ontario, localised heavier
rainfall amounts of over 100 mm are possible over areas adjacent
To Lake Ontario northward to Algonquin Park.

Heavy rain could also affect other parts of Quebec with amounts of
20 mm likely. At this time, the probability of rainfall amounts
exceeding 25 mm for these areas is around 40%. Heavier rain is
expected over the Maritimes and amounts in this area could exceed 50
mm.

The precipitation could mix with or turn into snow over parts of
South-Central Ontario and extreme Western Quebec as temperatures
approach the freezing mark north and west of the storm. A
Significant snowfall event could occur over Central Ontario.

B. Winds.

Most areas of Southern Ontario will be subject to very windy
conditions with possible severe gusts in excess of 100 km/h
especially along Western Lake Ontario and the Niagara Escarpment.
These gusts could cause broken tree limbs or in some cases uprooted
trees which may result in downed utility lines. Residual falling
leaves can also obstruct storm water drainage systems along roadways
particularly in urban areas. This combined with heavy rainfall could
increase the risk of flooding in some areas.

Very strong northeast winds will also affect eastern and Western
Quebec. There is a good probability of wind gusts exceeding 90
Km/h. Gusty winds can also be expected in the Maritimes especially
Monday night.

C. Waves.

There will be a risk for large waves along the Atlantic coast of
Nova Scotia especially along the south shore as wave activity begins
to increase Monday into Tuesday. These large waves could produce
pounding surf conditions.

3. Marine weather impacts and warnings summary.

Gale force winds are expected to spread to Canadian waters well in
advance of Sandy reaching the United States coastline. Gales are
expected on Monday over the Great Lakes, the St Lawrence seaway and
western Maritimes marine waters. There is a possibility of storm
force winds over southwestern marine areas of the Maritimes and on
the Great Lakes.

Also, higher than normal water levels are expected on the st
Lawrence River during high tide Monday evening and especially
Tuesday evening. This could result in coastal flooding in the
Quebec City region.
